The Splice Report does not open after clicking the Splice Report tool and selecting a splice location.
This issue may be related to the following bug, fixed in ArcFM 10.0.1.
MM41989: Splice Report Tool does not launch or give error if Report Name (Primary Display Field) contains characters colon(:) or slashes (/ \).
The workaround is to remove special characters from the primary display field of Splice features.
Visit the ArcFM Solution Resource Center for information about how to determine the primary display field for a feature.
